Demonstration of QoS-aware wireless protection scheme for video service in fiber-wireless access network

This paper proposes a wireless protection scheme with quality of service (QoS)-aware dynamic resource allocation for video service in the hybrid fiber-wireless access network. The proposed scheme introduces the optical network unit (ONU) with wireless function called WONU for wired and wireless services, and uses the wireless resource between the WONUs to protect the network against failure without deploying extra components. Moreover, a QoS-aware strategy based on the time-domain adaptive linear prediction and media delivery index is embedded in the protection scheme to guarantee the QoS of video service and improve the efficiency of bandwidth utilization. To evaluate our scheme, an integrated test-bed, which consists of passive optical network and wireless network, is constructed. The experimental results show that the protection scheme could effectively protect the video service with high QoS guaranteed and bandwidth utilization.
